i still have a 2nd set of klee2 PCBs in the drawer and i toy with the idea of building myself a eurorack module from it despite my backlog)! currently i shrunk it to 60HP using pushbuttons with built in LEDs (as seen on my LPG with gate controlled mode). i would replace the manual range selection switch by a voltage controlled switch.

what do you think? ideas?

cool idea... nice and small not so big . im still looking for a smal one.
do you share this files ? if not i understand ...but if you like it will be fine .

From a human factors point of view, the two buttons manual load and manual step need to be somewhere you can get at them, as they are by FAR the most used panel controls. Locate them together and out of the way of other switches, connectors and indicators. This is probably the most important piece of the panel layout.

I got my connectors away from my switches and knobs by locating them off to one side. It helps keep cable congestion away from those all important pushbuttons. While well compartmentalised for function, you may find that there are other ways to group that help keep track of steps. You probably will not use all of the merge, invert, etc switches as much as the pattern switches and the gate bus switches, and you'll hate them being in the way, so watch for that.

Oh and also the clock enable gets used a lot when you're programming. I don't think it has to be right next to your pushbuttons but it'll want to be somewhere you can feel for it._________________Garret: It's so retro.

I'll bear all of that in mind. I've kept the whole pattern, gate bus set up on the top half so it's separate and hopefully clear, but I might re-arrange the bottom half a bit.

I've tried to avoid some obvious labeling so the switch above the clock input is clock enable and the push switch above that is the clock step momentary switch. The same with the Load section so the load enable switch is directly above the Load in jack and the manual load is above that. I like my logical set up (all nicked from other people's designs it must be said ) but I can see what you mean about the advantages of not having a dirty great jack plug in the way right under my momentary switches.

It gives me something to ponder and, at the end of the day function may have to rule over form so I'll look at re-jigging it here & there.

Your input is much appreciated, I'm really keen to make some progress and have this up and running, it looks like such fun to play with!

A pleasure. I'm not saying my panel was perfect, but there were some major design decisions that worked and some I would do much differently after using the thing fairly constantly over a 2 year period. Grouping the connectors out of the way on a big panel like that is practical. Getting the glide. random and range select out of the way (although range select is another one you're likely to use a lot in practice) has worked for me._________________Garret: It's so retro.

this is how it looks in real (chnged the knob, though). the MIDI is a small pic based converter from marc bareille (papareil).
the whole sequencer is sold(!), however, i am working on a small eurorack module version for this awesome squencer...

Amazing. That does look really nice, and that green is a really nice colour. Everything I've seen of yours is really nice.

Im still deciding between sliders and a circular layout. Both have their pros and cons.

How did you find those 45(?)/60mm sliders? Are they long enough in practise? I had a novation controller and found the 45mm sliders a bit fiddly, although they were terrible cheap plastic ones anyway. Id love 100mm sliders...

Ive got one of your VC Clock PCBs now thanks to a kind person on here with the PWM so im going to incorporate that. Midi in i think ill leave external, for the DK/Fonik M2C, but it would be nice live. MIDI out would be an awesome addition but probably a bit complex for me.

Do you mind if I ask if the panel files are available? I like how compact your panel is for frac! Do you have any photos of the back? I'm curious how you mated the panel and pcbs. Thanks for any info, you've done a great job in my eyes.

This is what I ended up sending to photo print on aluminium. Received my "picture" today. It is not pure 3mm alu as I had hoped for. But a plastic laminate between two thin layer of aluminium. Very light but still quite stiff. The grey back color is very even and the hair line for the drill marks are all there so this looks like a quality print job. Sadly they only would take JPG so no guaranty the scale would hold up. Luckily that's not a problem on this build.

Panel size is a full 84HP 3U. Should be easy to drill, but not sure if I can use a circle saw to cut the sheet. I have some concern the heat might be a problem for the plastic.
